INTRODUCTION: Anemia is frequent in patients undergoing transcatheter aortic valve implantation (TAVI) with a strong negative prognostic impact. The prevalence and prognosis of anemia and separately of iron-deficiency anemia in contemporary patients are unclear. METHODS AND RESULTS: In total, 549 consecutive patients undergoing transfemoral TAVI were included in the single-center study. Baseline anemia was defined as a hemoglobin level <13g/dL in men and <12g/dL in women...

We here report the case of a stenosis of the CoreValve(®) system due to reduced mobility of prosthesis cusps for which a surgical replacement of the aortic valve was proposed. The exact mechanism leading to this impaired mobility of the leaflets is yet to be determined. We also underline the fact a transcatheter aortic valve implantation (TAVI) device can be replaced by a surgical replacement without excessive operative risks despite the patient being initially considered as high-risk.

Chronic Hepatitis B virus (HBV) infection is a major worldwide public health problem. Current direct-acting anti-HBV drugs target the HBV DNA polymerase activity, but the equally essential viral ribonuclease H (RNaseH) activity is unexploited as a drug target. Previously, we reported that α-hydroxytropolone compounds can inhibit the HBV RNaseH and block viral replication. Subsequently, we found that our biochemical RNaseH assay underreports efficacy of the α-hydroxytropolones against HBV replication. Therefore, we conducted a structure-activity analysis of 59 troponoids against HBV replication in cell culture...

Culex flavivirus (CxFV) is an insect-specific flavivirus infecting Culex mosquitoes, which are important vectors of West Nile virus (WNV). CxFV and WNV cocirculate in nature and coinfect Culex mosquitoes, including in a WNV "hotspot" in suburban Chicago. We previously identified a positive association between CxFV and WNV in mosquito pools collected from suburban Chicago in 2006. To further investigate this phenomenon, we compared the spatial and temporal distribution of CxFV during an interepidemic year (2011) and an epidemic year (2012) for WNV...

Opiate abuse in the United States (U.S.) is on the rise among the college student population. This public health crisis requires immediate action from professionals and stakeholders whom are committed to addressing the needs of prospective, current, and recovering opiate users using comprehensive prevention methods. Such approaches have been used to deliver primary, secondary, and tertiary intervention to alcohol and other drug users but are underutilized in the case of opiate abuse among college students in the U...

INTRODUCTION: For a long time, a bicuspid valve has been considered a contraindication to transcatheter aortic valve implantation (TAVI) due to worse procedural results. Currently available technologies are changing the scenario, with initial experiences reporting much better results with second-generation devices. AREAS COVERED: This review will analyze the risk and potential pitfalls of TAVI on bicuspid valves and will try ascertain how the use of a new-generation fully repositionable device, the Lotus Valve System (LVS), could improve procedural and clinical results in bicuspid anatomies...

Vascular endothelial growth factor B (VEGF-B) is a potent mediator of vascular, metabolic, growth, and stress responses in the heart, but the effects on cardiac muscle and cardiomyocyte function are not known. The purpose of this study was to assess the effects of VEGF-B on the energy metabolism, contractile, and electrophysiological properties of mouse cardiac muscle and cardiac muscle cells. In vivo and ex vivo analysis of cardiac-specific VEGF-B TG mice indicated that the contractile function of the TG hearts was normal...

Transcatheter aortic valve implantation (TAVI) is a rapidly evolving therapeutic modality currently available for patients with severe aortic stenosis (AS) that are unsuitable for surgery because of technical/anatomical issues or high-estimated surgical risk. Transfemoral approach is the preferred TAVI delivery route when possible. Alternative non-transfemoral access options include transaortic, trans-subclavian and transapical access. Other approaches are also feasible (transcarotid, transcaval, and antegrade aortic) but are restricted to operators and hospitals with experience...

BACKGROUND: Microarrays and RNA sequencing are widely used to profile transcriptome remodeling during myocardial ischemia. However, the steady-state RNA analysis lacks in sensitivity to detect all noncoding RNA species and does not provide separation between transcriptional and post-transcriptional regulations. Here, we provide the first comprehensive analysis of nascent RNA profiles of mRNAs, primary micro-RNAs, long noncoding RNAs, and enhancer RNAs in a large animal model of acute infarction...

Transcatheter aortic valve implantation (TAVI) has proven to be the standard of care for patients with prohibitive and high operative risk; today, it is considered a reasonable alternative to surgical aortic valve replacement in intermediate-risk patients. As indications for TAVI move toward patients at lower risk, safety aspects are becoming even more important. Furthermore, adequate patient selection is key for predictable procedural success with minimal complications, translating into an optimal clinical outcome...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been reported to be advantageous over surgical aortic valve replacement owing to the low incidence of prosthesis-patient mismatch (PPM) and large effective orifice area (EOA). However, data on TAVI for extremely small annuli are limited. The present study aimed to compare post-procedural hemodynamics and morphology between 20-mm and 23-mm Sapien XT (SXT) transcatheter heart valves (THVs) with extremely small annuli (<314mm(2))...

Aims: Transcatheter aortic valve implantation (TAVI) has developed from a procedure for patients with aortic stenosis inoperable or high risk for surgery, into a treatment option even for intermediate risk elderly patients. This development has been facilitated by the clinical learning curve and constant improvements of transcatheter heart valves used. We present total 1-year results of SOURCE 3, the European post-approval multicentre registry of the latest generation balloon expandable SAPIEN 3TM (Edwards Lifesciences, Irvine, CA, USA)...

BACKGROUND: Despite promising results following transcatheter aortic valve implantation (TAVI), several relevant challenges still remain. To overcome these issues, new generation devices have been developed. The purpose of the present study was to determine whether TAVI with the new self-expanding repositionable Evolut R offers potential benefits compared to the preceding CoreValve, using propensity matching. METHODS: Between June 2007 and November 2015, 2148 consecutive patients undergoing TAVI either CoreValve (n=1846) or Evolut R (n=302) were prospectively included in the Italian TAVI ClinicalService® project...

BACKGROUND Sutureless aortic valves were introduced to facilitate minimally invasive aortic valve surgery. Since sutureless aortic valves are a feasible procedure, we evaluated if any benefits could be identified in severe high-risk patients with active infective endocarditis of the aortic valve. MATERIAL AND METHODS Between April 2014 and April 2015, a total of 42 patients received a sutureless Perceval® aortic valve (Sorin Biomedica Cardio Srl, Saluggia, Italy) for different indications. Nine of these patients (median age 71 years, range 47-83 years) suffered from active infective endocarditis, including four patients with prosthetic aortic valve endocarditis...

Aims: Treatment of tricuspid regurgitation (TR) is common after surgery for mitral and/or aortic valves. The prognostic role of moderate to severe TR in patients undergoing mitraclip or transcatheter aortic valve implantation (TAVI) is not well-defined. Thus, the aim of this article is to perform a systematic review and meta-analysis of articles valuing the prognostic role of TR for patients undergoing mitraclip and TAVI. Methods and results: Articles were searched in Pubmed, Cochrane Library, Google Scholar and Biomed Central in September 2016...
